Universal Citation: 2 DE Admin Code 6F.64

Current through Register Vol. 28, No. 3, September 1, 2024

Standard:

01 (DE Revision) Cones (see Figure 6F-7) shall be predominantly orange and shall be made of a material that can be struck without causing damage to the impacting vehicle. Cones shall be a minimum of 28 inches in height for all operations.

02 (DE Revision) Except as noted in Paragraphs 3A, 3B and 3C, cones shall not be used for nighttime operations. Retroreflectorization of cones that are 28 to 36 inches in height shall be provided by a 6-inch wide white band located 3 to 4 inches from the top of the cone and an additional 4-inch wide white band located approximately 2 inches below the 6-inch band.

03 Retroreflectorization of cones that are more than 36 inches in height shall be provided by horizontal, circumferential, alternating orange and white retroreflective stripes that are 4 to 6 inches wide. Each cone shall have a minimum of two orange and two white stripes with the top stripe being orange. Any non-retroreflective spaces between the orange and white stripes shall not exceed 3 inches in width.

Option:

03A (DE Revision) Due to the unique and temporary nature of traffic management for special events, including complex traffic shifts to accommodate ingress and egress, retroreflective cones may be used at night during planned special events.

03B (DE Revision) Retroreflective cones may be used in lieu of drums during a single nighttime emergency operation.

03C (DE Revision) Retroreflective cones may be used to supplement a mobile striping operation.

04 Traffic cones may be used to channelize road users, divide opposing vehicular traffic lanes, divide lanes when two or more lanes are kept open in the same direction, and delineate short duration maintenance and utility work.

Guidance:

05 Steps should be taken to minimize the possibility of cones being blown over or displaced by wind or moving vehicular traffic.

Option:

06 Cones may be doubled up to increase their weight.

Support:

07 Some cones are constructed with bases that can be filled with ballast. Others have specially weighted bases, or weight such as sandbag rings that can be dropped over the cones and onto the base to provide added stability.

Guidance:

08 Ballast should be kept to the minimum amount needed.
